The average of 10 members is 15665. If 2 members have 20000 then what is the average of remaining?

• 20000*2+8*x=15665*10
  8x=156650-40000
  x=116650/8
  x=14581.25(ans)

• 10 person /10=15665
  2 members have 20000
  (20000+8 person) / 10 =15665
  (20000+8 person)=156650
  8 person =156650-20000
  8 person =136650
  so
  the average of 8 person=136650/8
  =17081.25

• x/10=15665
  x=156650
  y/2=20000
  y=40000
  x-y=116650
  (x-y)/8=14581.25

• 10 person/10=15665
  10 person=156650
  2 person/2=20000
  2 person=40000
  8 person/8=10 person - 2 person
  8 person/8=156650-40000
  8 person/8=116650
  8 person=116650*8=14581.25(Ans)

• it is not mentioned that AVERAGE of 2 members is 20000..
  we can take it as sum of two members is 20000.
  so ...average of 10 members is 15665*10=156650
  now average of remaining 8 members is (156650-20000)/8 = 136650/8 = 17081.25

• the avg of 10 members is 15665 that means,
  10 persons/10=15665
  (2persons+8 persons)=15665*10
  (2*20000+8x)=156650
  8x=156650-20000
  x=116650/8
  x=14581.25
  so, the average of remaining 8 members are,14581.25
